GSW: The Warriors suck currently with the team seeming to feel like they have lost hope. Wiggins has not been playing up to the standard that the warriors are wanting so what if they could get rid of him for Steph's brother. Not only would Seth support Curry just like Thanasis for Giannis but he also offers great offensive scoring off the bench. in this trade they get more depth with Holmes who can fit in perfectly as a backup Centre filling out the big man position they have struggled with for so long. Lastly to replace Wiggins in his position we have Kleber who adds some depth.
Mavs: For Dallas to really contend they need a more experienced player in the SF position. Wiggins fits that perfectly adding on the defensive end with hustle and desire, although he is struggling offensively he could thrive in a new system with Luka. He brings a veteran mindset knowing what it's like to win a championship so he can bring a mentality in the locker room that could carry them through the playoffs. They get Joseph to fill out the whole left by Curry and Santos a young piece that could develop for the Mavs in the future.
